7 Claims.

This invention relates to improvements insealing means for casement windows and has refer ence more particularly to a weather strip that can be employed in connection with any ordinary 5 casement window.

It is becoming increasingly popular to employ metal window frames and sash in building construction; such window construction, however, is not weather tight, as it is very diflicult to effect lo such a close fit between the casement frame and the sash that air and dust will not enter. To make this type of window Weather proof, various kinds of weather strips have been invented and used.

15 It is the object of this invention to produce a weather strip that can be interposed between the casement frame and a screen or storm window frame and which can be attached to the latter so that both may be applied or removed as a unit.

20 Another object of the invention is to produce a seal or weather strip that can be used by itself, as well as in connection with an auxiliary frame.

In order to explain this invention so that it can be readily understood, reference will be had to the accompanying drawing inwhich the in.-

vention has been illustrated in its preferred form, and in which:

Figure l is a side elevation showing a corner of a casement window with the improved weather 30 strip in position between the casement frame and the screen frame;

Figure 2 is a section taken on line 2-2, Figure 1, portions being shown in perspective;

Figure 3 is a top plan view'of the improved 35 weather strip;

Figure 4 is a section taken on line 44, Figure 3; and

Figure 5 is a section similar to that shown in Figure 4, butshowing the weather strip attached 40 to a casement window without the use of the auxiliary frame.

In the drawing reference numeral 6 designates a casement frame and reference numeral 1 a window sash. These two parts are of conven- 45 tional construction, each being formed from a special Z-bar having a central web 8 and flanges 9. Applicant claims no novelty in the frame construction, but the parts have been illustrated in detail for the purpose of better explaining his invention. When the window sash is closed, the parts occupy the position shown in Figure 2 from which it will be seen that the corresponding flanges of the frame and the sash overlap.

It is customary to apply to casement windows 55 of this type a woven wire screen like that indicated by reference numeral it in Figures 1 and 2, and this is secured to a screen frame which has been indicated in its entirety by reference numeral i l. The screen frame illustrated in the drawing is of old and well known construction, but for the purpose of making this description complete, the screen frame construction will be described to some extent, as follows:

The screen frame is made from a single piece of sheet metal bent into substantially rectangular 10 form. The top of the frame has been designated by reference numeral E2, the outer vertical side by reference numeral i3, and the bottom by reference numeral i i. The top is bent downwardly along line it: and thence outwardly as indicated at It and thence downwardly as indicated at H. The bottom. is bent upwardly so as to form a side wall i8, and thence outwardly to form the bottom i9 of a longitudinally extending groove. The edge of the bottom i9 and of the side ll overlap so as to form a rigid assembly. The screen 50 is positioned in the groove and held in place by a bar 2%. Such screen frames are in common use and. are secured to the casement frame by means of clips 2i of Z-shape and these clips are secured to the casement frame by screws In order to effect a weather seal between the. sash and the casement frame, a weather strip has been provided that has been designed with special reference to the position in which it is to be used in the combination illustrated in Figures 1 and 2.

The weather strip consists of an elongated metal strip 23, which ispreferably made from sheet steel, although it can be made from any other suitable material, such as brass or copper. The strip is offset longitudinally so as to form two surfaces at different levels, the lower surface being indicated by reference numeral 2d; the edge of the higher surface shown in Figure 4 has been designated by numeral 25, and this has been bent downwardly and thence reversely so as to form a channel 28.1 The edge of the lower portion has been designated. by reference numeral 21 and this has also been bent reversely so as to form a channel 28. Resilient sealing members are attached to the edges of the weather strip 23 and interlocked with the latter by means of the reversely bent edges 25 and El and the corresponding channels 26 and 28. The sealing strips have been designated by reference numerals 29 and 36. The sealing strip 29 is formed of a sheet of rubber, or other similar material, bent into the shape shown in Figure 4 and allowed to set in this shape, and such a strip can readily be at- 5 tached to the weather strip 23, and when so attached will be quite firmly held in place. The resilient strip 30 differs from the one marked 29 in this, that the under portion thereof is provided with an opening 3|, which permits the strip to be compressed to a greater extent than if it were solid, and this makes it possible for it to accommodate itself to every irregularity in the contacting surface of the sash. The strip 23 is provided with spaced openings 32 for the reception of screws 33 by means of which it may be secured to the bottom 14 of the screen frame. When a screen frame is not used, the weather strip can be attached to the casement frame in the manner shown in Figure 5, in which position it can be held by screws 33a that have threaded connection with openings in the casement frame 6. When the weather strip is used in the ab-- sence of the screen or storm sash frame, ferrules 34 of a proper length are positioned between the under surface of the strip and the outer surface of the casement frame flange in the manner shown in Figure 5.

From the above description, when taken in connection with the drawing, it will be apparent that by means of this weather strip, a weather tight seal can be provided between the window casement frame and the window sash, either with, or in the absence of the screen frame.

Attention is also directed to the fact that two separate resilient sealing strips are employed, one of which effects a seal with the sash and the other a parallel seal with the casement frame. Such weather strips can be manufactured in suitable lengths and cut to fit any size window opening. Although they are entirely separate from the screen frame, they can be readily attached thereto in the manner shown in Figure 2, and this facilitates the application of the weather strip to the casing. It is, however, possible to effect the seal in the manner shown in Figure 5 and this manner of employing the weather strip is indicated where screens are not used.

In the above, reference has been made to the fact that the metal strip 23 is formed with surfaces on two levels and one of the reasons for this construction is that the resilient sealing strip 30 has a portion 35 that is reversely bent and this is positioned on top of the lower longitudinal surface of the strip so that the upper surface of the weather strip will be substantially in a single plane. The outer wall of strip 29 has been shown as extending upwardly above the surface of the weather strip and it therefore overlaps the vertical side I3 of the screen frame when in position. This feature of the construction is not of any considerable importance, and the vertical wall of strip 29 can be made of a height different from that shown without effecting the sealing function.

Having described the invention what is claimed as new is:

1. A device for effecting a seal between a casement frame and sash, comprising a metal strip,

a sealing strip of resilient material attached along each edge thereof, said resilient strips projecting unequal distances from one surface of the metal strip, the thinner and the thicker resilient strips being adapted to contact respectively with the casement frame and the sash.

2. A device for effecting a seal between a casement frame and sash, comprising a metal strip, a sealing strip of resilient material attached along each edge thereof, said resilient strips projecting unequal distances from one surface of the metal strip, the thinner and the thicker resilient strips being adapted to contact respectively with the casement frame and the sash, and means forming an interlock between the metal strip and the resilient strips.

3. A device for effecting a seal between a casement frame and sash, comprising a metal strip having its edges reversely bent into spaced para-llel relation with one side, whereby two channels are formed, and resilient sealing strips having attaching edges positioned in the channels, said strips being folded outwardly over the bent edges.

4. A device for effecting a seal between a casement frame and sash, comprising a metal strip having its edges reversely bent into spaced parallel relation with one side, whereby two channels are formed, and resilient sealing strips having attaching edges positioned in the channels, said strips being folded outwardly over the bent edges, one of the resilient strips being thicker than the other.
